We have developed a novel miniature micro-lensed fibre probe for Raman spectroscopy. The fibre probe consists of a single negative-curvature fibre (NCF) and a spliced, cleaved, micro-lensed fibre cap. Using a single NCF, we have minimized the generated Raman background from the silica and maintained the diameter of the probe to be less than 0.5 mm. In addition, the cap provided fibre closure by blocking the sample from entering the hollow parts of the fibre, enabling the use of the probe in in-vivo applications. Moreover, the micro-lensed cap poses an improved collection efficiency (1.5 times increase) compared to a cleaved end cap. The sensing capabilities of the micro-lensed probe are demonstrated by measuring different concentrations of glucose in aqueous solutions.

我们研发了一款面向拉曼光谱检测的新型微型微透镜光纤探针。该探针由单根负曲率光纤（negative-curvature fibre, NCF）以及经熔接、切割加工的微透镜光纤端帽组成。通过采用单根负曲率光纤，我们有效抑制了二氧化硅基质产生的拉曼背景信号，并将探针整体直径控制在0.5毫米以内。此外，该端帽可阻挡样品进入光纤中空区域，实现光纤端口的封闭，使得该探针可应用于活体检测场景。进一步而言，相较于传统切割式端帽，该微透镜端帽的信号收集效率提升至原有水平的1.5倍。最后，我们通过检测不同浓度的葡萄糖水溶液，验证了该微透镜光纤探针的传感性能。
